Goniosurgery for prevention of aniridic glaucoma
Chen TC; Walton DSArchives of Ophthalmology 1999; 117: 1144-1148
OBJECTIVE: To report the long-term success and complications of modified goniosurgery to prevent aniridic glaucoma, an entity that typically is difficult to control medically or surgically. DESIGN: A retrospective review of the medical charts. RESULTS: Fifty-five eyes of 33 patients with aniridia without glaucoma, who underwent goniosurgery were identified. Ninety-one procedures were performed on the 55 eyes by one surgeon (DSW). Each eye had an average of 1.65 procedures and an average of 200° of goniosurgery. Average age at time of initial goniosurgery was 36.6 months. There were no operative complications. No eye had a decrease in visual acuity at last follow-up. All eyes had a preoperative intraocular pressure (IOP) of less than 21 mmHg. At last follow-up (average, nine years six months; range, eight months to 24 years), 49 eyes (89%) had IOPs less than 22 mmHg without medications. The remaining six eyes (11%) had IOPs of 22 mmHg or less with up to two types of eyedrops. CONCLUSIONS: Without prophylactic goniotomy, aniridic glaucoma may be expected in half the patients, and when it occurs, it is extremely difficult to control. Prophylactic goniosurgery in selected eyes of young patients with aniridia may be effective in preventing aniridic glaucoma.
